灾害链、不确定供求和复杂应急资源分配网络的动态配置

Multi-period optimal scheduling model of complex emergency resource allocation networks based on disaster chain and uncertain demand and supply

摘要:

基于灾害链、不确定供求和多周期情景,研究三层复杂应急资源分配网络应急资源的动态优化配置模型。该模型建立了三个带有主次关系的目标函数,分别为应急资源调度总时间最短、受灾人员损失最小、应急资源运输总费用最小,并从应急资源供给和应急资源需求等方面建立了相关约束条件。基于应急限制期约束对模型的多目标函数进行了转化,对相关参数进行了去模糊化处理,在此基础上给出了具体算法,并用算例验证了模型和算法的有效性和可行性。

Abstract:

According to the disaster chain scenarios of emergency event and emergency resource allocation network with three layer structure, a multi-period optimal scheduling model of emergency resource allocation networks based on disaster chain and uncertain demand and supply is set up. Three objective functions with priority (the shortest response time, the minimal loss of personnel loss and the minimal transportation costs) and the constraints based on the emergency resource demand and supply are set up. Multi-objective functions are converted based on the response time constraint of each affected-area. Defuzzification strategies and specific algorithm is provided. The effectiveness and feasibility of this algorithm is verified by the sample application.
